The Problem
Many construction tasks require frequent kneeling, squatting, or stooping because the work is close to the floor. Kneeling on a hard surface puts a lot of direct pressure on your knee, while squatting puts stress on the tendons, ligaments, and cartilage of the knee joint. Working in either position often or for long periods of time can lead to knee problems, including knee osteoarthritis.
If you work in a stooped position, there is stress on your lower back as well as your knees, possibly leading to back pain and even a serious back injury.
One Solution
Use a portable kneeling creeper with chest support. When the job requires kneeling or squatting to work at floor level, these devices will reduce the stress to your knees, ankles, and lower back.
How It Works
Kneeling creepers are available with removable seats and cushioned knee supports. They are very low and have 2 to 3 inch casters. The knee supports on one model are only ¾ inch above the floor. The cushioned knee supports reduce the pressure on your knees, just as ordinary knee pads do.
Some models are available with an adjustable cushioned chest support. It is useful when doing prolonged floor-level jobs like tile setting and concrete patching. It helps support your weight, reducing back strain and some of the pressure on your knees.
Benefits for the Worker and Employer
Kneeling creepers provide support when work must be done in awkward and stressful positions. They reduce stress on the knees and lower back, and can help prevent serious muscle and joint problems. Since work can be done with less discomfort and pain, productivity often also increases.
Kneeling creepers allow workers to move around more easily and quickly, and may also have an area where tools can be conveniently placed.
These devices can be used to assist injured workers retuning to the job, since they can work with less stress to their knees and back.
Approximate Cost
Kneeling creepers without the chest support cost around $200 and the optional adjustable chest support is around $75.
